Method of Multiple File Streaming Service Through Playlist in Mobile Environment and System Thereof

Abstract

A method and system of streaming content media files uses a Portable Terminal. In the event of streaming multiple content files in a mobile environment, the method combines multiple content files into one streaming file through the Playlist Generator provided for the Streaming Server and then streams the entire file at once to a Portable Terminal in order to resolve problems with the existing technology, wherein after streaming for 1 content file is all completed, one must request the Streaming Server for another session again in order to stream subsequent content files.

1 . A streaming method that can be implemented on a streaming server and that allows streaming of multiple content files at once, without attempting to reconnect to said streaming server to establish a separate session for each content file to be sent to a portable terminal, when multiple files are transmitted to the portable terminal from the streaming server, the method being for streaming of multiple files through a playlist file in a mobile environment, the method comprising:
 selecting 2 or more content files;   generating one playlist file for said content files via a playlist generator to prepare a streaming service; and   streaming said content files on the playlist file to the portable terminal as one file.   
   
   
       2 . The method of  claim 1  for streaming multiple files through the playlist file in the mobile environment, further comprising applying a real time update to the playlist file during streaming to the portable terminal. 
   
   
       3 . The method of  claim 1  wherein said selecting said content files set up in a content provider or web server that provides content files. 
   
   
       4 . The method of  claim 1  wherein said selecting said content files takes place in an interactive mode where a user of the portable terminal selects at least one file among the content files after connecting to a website. 
   
   
       5 . The method of  claim 2  wherein said applying the real time update includes in an event that a user of the portable terminal, in a middle of receiving streamed files, modifies, adds or deletes a content list of the playlist file which is being streamed after the user connects to a website, the modified, added, and deleted content list is streamed. 
   
   
       6 . The method of  claim 1  wherein said preparing said streaming service comprises:
 performing a validation check on content files that are selected by the playlist generator;   preparing the playlist file;   storing playlist files in a specific media folder of the streaming server; and   generating a streaming link for said specific media folder on an Internet page of a website.   
   
   
       7 . The method of  claim 6  wherein said performing said validation check includes validating a codec of each file and encoding a parameter of each codec. 
   
   
       8 . The method of  claim 7  wherein said performing said validation check includes performing a validation check on each file individually or collectively. 
   
   
       9 . The method of  claim 6  wherein said playlist file includes a sequence number, location information, and option information. 
   
   
       10 . The method of  claim 1  wherein said streaming said content files on the Playlist as one file includes:
 selecting a streaming link for the playlist file by connecting to an Internet page of a website using a browser of the portable terminal; and   wherein said playlist file is streamed as one file to the portable terminal without attempts of reconnection as said streaming link is selected, in said mobile environment.   
   
   
       11 .

       12 . The method of  claim 1  wherein said content files include advertisement content files, wherein the advertisement content files are combined with other content files to generate said playlist file through said playlist generator, and wherein advertisement content files and other content files are streamed sequentially as one playlist file to the portable terminal, in said mobile environment. 
   
   
       13 . The method of  claim 1  wherein the playlist generator that generates said one playlist, in said mobile environment, can set up a random access function that allows a user of the portable terminal random access to at least one of said content files contained in the playlist file. 
   
   
       14 . The method of  claim 13 , further comprising in the mobile environment, setting up a prohibited area that bars random access by the user of the portable terminal to at least one of said content files. 
   
   
       15 . The method of  claim 1  wherein the playlist generator that generates said one playlist file is adapted to set up a track move function that allows a track move by a user of the portable terminal for at least one of said content files contained in the playlist file.
